Communication Platform HART revision 5 or revision 7 (field selectable) HART revision 5 or revision 7 (field selectable) FOUNDATION TM fieldbus Protocol. MAU 121 (Entity model IS) and MAU 511 (FISCO IS) profiles powered from H1 segment, power change on transmit. HART DNGP Dashboard PC Interface, Modbus(R) communication protocol
Signal – Supply 4-20 mA control signal No external power required Supply pressure: 20 – 150 psi (1.4 – 10.3 bar) 4-20 mA control signal. No external power required. Supply pressure: 20 – 100 psi (1.4 – 7 bar) ___ 4-20 mA control signal. 24 Vdc power supply. Combination of 4-20 mA and 24 Vdc (4-wire device) Position Input Signal: 4-20 mA (Split range: menu selectable and adjustable – min 4 mA signal range). Cycle Counter Feedback Signal: Single Terminal +24 Volts
Description Supporting HART communications over the 4-20mA signal, the SVI II AP digital valve positioner is suitable for control systems with 4-20mA signaling. The SVi1000 supports HART communications over the 4-20mA signal, making it a superior choice for control systems with 4-20mA signaling.  

___

 The Masoneilan SVI II ESD can operate with a 4-20mA signal, 0-24Vdc, or a combination of both. The DNGP provides accurate control valve positioning with zero steady state bleed gas.
